Wheat field herbicide composition

Abstract

The invention belongs to the technical field of pesticides, and especially discloses a wheat field herbicide composition. The wheat field composition comprises a component A and a component B according to a weight percentage ratio of 1-500:500-1, wherein the component A is 2,4-DB and its derivatives, and the component B is one or more of sulfonylurea, aryloxyphenoxypropionate, triazolopyrimidines, triazoline-ketones, pyrazoles and synthetic hormones. The composition has a wide weed control spectrum, can prevent and treat grassy weeds and broad leaf weeds, has a very good synergistic effect, has an obvious synergistic effect than single use of preparations, has a fast weeding speed and is highly safe to wheat.

Description

(1) Technical field [0001] The invention belongs to the technical field of pesticides, in particular to a wheat field herbicide composition. (2) Background technology [0002] At present, weeds in wheat fields mainly include broad-leaved weeds and gramineous weeds. With the use of herbicides for many years and the particularity of weeding in wheat fields, there are more and more resistant weed species and larger areas; With simple compounding of dimethyltetrachloride, fluroxypyr and other herbicides, the effect of resistant Artemisia sorenzo and Swamp's weeds is getting worse and worse. Resistant wild oats and brome are treated with a single grass herbicide such as fluorine The effects of pyrasulfuron-methyl and clodinafop-propargyl are getting worse and worse, and most of the resistant weeds in wheat fields are gramineous and broad-leaved weeds together in the field. [0003] 2,4-D-butyric acid belongs to the growth hormone herbicides of phenoxycarboxylic acids. It can...

[0003] 2,4-D-butyric acid belongs to the growth hormone herbicides of phenoxycarboxylic acids. It can effectively control some annual or perennial broad-leaved weeds, and can also effectively control various sedges. Poor activity of grass

[0005] There are few reports on the application of 2,4-D butyric acid in wheat fields, and there are even fewer reports on the compounding of 2,4-D butyric acid with common herbicides in wheat fields
